Towards an Excursion Flora for Austria and all the Eastern Alps
Fischer MA
Pages 5-33
Full reference | Abstract | Full text PDF

ABSTRACT: This is on the one hand an announcement of the two-volume Fourth Edition of the Excursion Flora for Austria expanded by also including the remaining parts of the Eastern Alps (chapter 1), and on the other hand a rough survey of the flora of the Eastern Alps in connection with the main vegetation types (chapter 2). The geographical scope includes, besides Austria, the entire Eastern Alps from the Rhine valley in E Switzerland (Grisons) to the Vipava valley in SW Slovenia. Volume 1 mainly contains comprehensive introductory chapters like introductions to plant morphology, taxonomy, and nomenclature, as well as a sketch of ecomorphology and habitat ecology, a survey of vegetation types (phytosociology) and floristic peculiarities of the different natural regions, a rough history of floristic research, a detailed glossary including the meaning of epithets, etc., and drawings of several plant species characteristic of the flora covered. The structure of the keys concentrated in volume 2 is explained: besides the descriptive traits, they include for each taxon comprehensive ecological and plant geographical data, as well as information about Red Lists of the countries involved, plant uses, and taxonomical problems. Genus names are given not only in German, but also in the Romansh (Rumantsch Grischun), Italian, and Slovenian languages. In chapter 2, some important chorotypes including endemics are characterised, and an overview of floristic diversity (lists of exemplary taxa) in accordance with the main and most characteristic vegetation types is presented.

Pages 35-69
Full reference | Abstract | Full text PDF

ABSTRACT: An overview of floristic and taxonomic research on vascular plants in Bulgaria during the period of 2005-2016 has been made. The Bulgarian flora currently comprises 4064 species, belonging to 921 genera and 159 families. About 490 published papers were checked, in which 127 species were reported for the first time for the country by Bulgarian or foreign botanists, 11 of these taxa being ones new to science, while 51 are aliens. In the papers checked, 17 subspecies (two of them new to science) and 18 hybrids (four of them new to science) were also reported for the first time for the country, nine species were confirmed, and another 78 were unconfirmed, synonymised, or erroneously reported. In numerous papers, new localities for various species in different floristic regions in Bulgaria were reported. The books Flora of the Republic of Bulgaria Vol. 11, Red Data Book of the Republic of Bulgaria Vol. 1. Plants and Fungi, Atlas of Endemic Plants in Bulgaria, Invasive Alien Species of Vascular Plants in Bulgaria, Proceedings of Balkan Botanical Congress IV, etc., were published during the given period.

KEY WORDS: Bulgaria, flora, literature, vascular plants

ABSTRACT: As a European endemic restricted to a few European countries, Geum bulgaricum is here treated as a “target species” or “species of European concern”. Although of great international significance, its distribution is insufficiently known. Based on several years of field studies and analyses of herbarium and literature data, we have determined that G. bulgaricum is a Balkan endemic plant distributed in Albania, Bosnia and Herzegovina, Bulgaria, Montenegro, and Serbia. Although the range of its distribution is divided into two main parts - “eastern” (the Rila Mountains in the Rhodope-Rila mountain system) and “western” (several mountains in the Dinaric system and one isolated population in the northeastern part of the Scardo-Pindic system) - in fact all populations are grouped into four disjunctions. Based on our studies of extensive chorological data and estimation of the number of individuals and condition of the populations, we have now defined G. bulgaricum as IUCN NT in Albania and Montenegro, and VU D2 E in Serbia. Also, we have confirmed its status as NT in Bulgaria, and changed its status from LR to VU D2 E in Bosnia and Herzegovina. The species is most often found in alpine and subalpine acidophilous (Juncetea trifidi) and calcicolous (Elyno-Seslerietea) grasslands and swards, as well as in the vegetation of scree habitats (Thlaspietea rotundifolii), rocky crevices (Asplenietea trichomanis), subalpine belts of krummholz pine (Roso pendulinae-Pinetea mugo), and very localised serpentine outcrops. Its ecological optimum is in the subalpine and alpine vegetation belt. Furthermore, we here provide the first insight into the differentiation of its populations. We found that the Rhodope-Rila and Dinaric populations are slightly differentiated on the morphological level and well differentiated with respect to genome size. The name Geum bulgaricum is lectotypified.

Beech forests (order Fagetalia sylvaticae Pawlowski 1928) in Serbia
Karadžic B
Pages 91-107
Full reference | Abstract | Full text PDF

ABSTRACT: Beech forests occupy considerable areas in Serbia. The principal aims of this research were to detect variability patterns and determine biodiversity components in Serbian beech forests. The K-means clustering of a data set comprising 270 relevés and more than 500 species revealed seven ecologically interpretable groups of beech forests in Serbia. The groups are presented in a synoptic table, with calculation of diagnostic species. Canonical correspondence analysis indicates that the altitudinal gradient is the main factor affecting diversification of the investigated forests. Species richness and alpha diversity are greatest in beech forests of ravine habitats.

KEY WORDS: altitudinal gradient, alpha diversity, beech (Fagus sylvatica) forests, canonical correspondence analysis, K-means clustering, species richness

Rediscovery of the endemic species Chara rohlenae Vilh. 1912 (Characeae) - believed extinct - on the Balkan Peninsula
Blažencic J &Stevanovic B
Pages 109-115
Full reference | Abstract | Full text PDF

ABSTRACT: The species Chara rohlenae was described more than a hundred years ago (in 1912) as a species new to science on the basis of herbarium specimens collected from the Mratinje locality in Montenegro. In addition, there were some other herbarium specimens of this charophyte originating from Greece (collected in 1885) and also ones from Bosnia and Herzegovina (collected in 1925), which, however, were taxonomically determined in different ways and not clearly identified as belonging to the species C. rohlenae. For such a long period of time thereafter, no new data on the presence of the given species in the Balkans were recorded, and for this reason the species was considered to be extinct (EX glob ?) in accordance with IUCN criteria. However, during botanical surveys conducted in 2010 and 2012, C. rohlenae was rediscovered on the Balkan Peninsula, in the Mokra Gora Mountain (a spur of the Prokletije massif) in Serbia. This finding confirms existence of the species in the wild. Morphological characteristics of the newly found specimens of C. rohlenae from Serbia are investigated in the present study.
